My invention relates to molds and more particularly to molds for moldingbutter and -other similar substances prior to cutting the same intosquares. Y

Anobject of the-presentinvention is to provide a mold wherein the sideand end walls maybe adjusted laterally so as to facilitate dumping ofthe mold. vvFurther the invention provides-a mold of l0 'this characterwhich is durable in construction andwill withstand moistureand roughvtreatment to which the mold is. subjected.

With the preceding and other. objects and advantages in mind, theinvention consists in the novel combination of elements, construe#ktions and arrangements of parts and opera.-`

tions to be hereinafter more fully described, claimed and illustrated inthe accompanying drawings, wherein: Y `Figure 1 is a top plan view of amold con.-

structed in accordance with my invention;

Fig. 2 is afragmentary vertical section talr- .en on line 2 2 of Fig. 1;

' Fig. 3 is a fragmentary bottom plan View ofthe same; and

MFig. 41s afragmentary elevation of a slightly modified embodiment ofthe inven-` tion.

Referring to the invention in detail a rec- 80 tangular bottom 5 havingbevelled edges 6 is provided. Side walls 10 arise from the longitudinaledges of the bottom 5 while end walls 11 arise from the remaining edgesof the bottom. The innerl faces ofthe side walls at their lower edgesare vformed with longitudinally extending recesses having al bevelledside wall 7 opposed to the bevelled edges 6 and a right angular upperwall or shoulder 7a, the latter resting upon the upper face of 4 0 thebottom, and constituting fulcrum points for the walls.

Extending along the lower edges of the side and end walls and upon theouter faces of the latter are cleats 8. Relatively long bolts 9extendtransversely through the cleats and associated walls. These boltsextend through longitudinal bores 10a formed in the bottom between itsupper and lower faces. At the inner ends of the bores 10a recesses 11are formed in the under face of the bottom into 1929. semi No. 382,168.j which theA ends of the bolts project. Nuts 12 .i

Aare accommodated in these recesses and are engaged with the bolts tomaintain tension on the lower ends of the side and'end walls.

Reinforcing rails substantially L-shaped in v:i5 y

crosssection embrace the upper edges of the lwalls 10 and are securedthereto by.dowel pins 14. As disclosed particularly in Fig. 1 vthe railshave one sidebevelled as indicated at 15, and some of the dowel pinsextend at V6.0

vi'ded with rails 16identical to the rails 13 and which areAprovided'with'lateral extensions lctwhich project beyond thev sidewalls10. Recesses 17. are providedinV the inner facesof the rails 16 forthereception of the ends-of the rails 13.--V Each of therecessesl 17 hasoneofits side walls bevelled in the same Y plane as the bevelled ends 15.as indicated at '.70 18.f.

The extensions16a at each side of the ,mold are provided withlongitudinallyalined horizontally extending bores 19 throughwhich a rod20 passes. Oneend of each of the'rods is threaded into a disk 21'securedto they outer face of the extensions of one ofthe rails 16. The oppositeendsof thev rods pass through the extensions of the other rails 16andare provided with wing nuts 21 which 'are adjustable to place therods under tension or produce slack therein. By threading the rods 20into the dislrs21V splitting'of the ex- -tensions is prevented when theends are subj ected totorque dueto tightening of the nwing vnuts. Y

Normally the wing nuts Vare adjusted against the adjacent rails 16 tomaintain the rodsunder tension and thereby hold the side andy end wallsin a true perpendicular 'position. When it is desired to dump the moldthe wing nuts are loosened; Incident to loosening of the wing nuts thewalls swing to the Vangular position-'disclosed indottedlines in Fig. 2.This movement of the walls ishad by reason of the lowerends being Vundertension of the bolts9 and the parts 7 constituting fulcrurns for thewalls. In other. words,v when the rods 2O are slaclened the side and endwalls swing outwardly'to an inclined posi- CII tion, thus facilitatingdumping of ther mold contents. v

When the winged nuts are adjusted to tension the rods the end walls aredrawn towards each other and as they move the bevelled walls 18 of therecesses 17 ride over the bevelled surfaces 415fof the railsandcause-the side wa'llstoimove inwardly to theupright position.

In the modification disclosed ,in vFig.V t the ends of the railsare-rounded "atoneside as indicated at 22 and one side of the recesses17 are similarly shaped to receive the ends of the rails. I Inthis formofthe l invention cir- Y cular wear plates 23 are secured to the'outerlnuts 21, anditoipermitthe lattertofturn freely.
